In book printing when blocks' are used which are of a lesser height than that required for the general type matter employed, said blocks must be packed up to this proper height. Hitherto it has been usual to ascertain the "packings neededby trial with the block in the set up matter, a processwhich is awkward, and often entails rectifications after proofs have been taken; 1 i

Thepresent invention obviates this trial and awkward method of packing which isnot highly acourate,is a waste of time and diminishes the output capacity of the printing press, by creating a simple and ingenious device which renders it possible to ascertain the required amount of packing in the shortnpossible time. w

The'accompanying drawings'show as an example one constructional form of the invention. I f I Fig. 1 isa front view of the device. Y Fig. 2 is a similar view .with the front cover removed and Fig. 3 is a plan view. The essential component part "ofthe invention is a gauge indicated generally inthe drawings at 1 and includes atwov armed lever 8, which is connected toan indicating device 2, 3. The gauge leverefi is pivoted be- :tween the recessed back-wall 1 and the removable front wall 5 ofthe housing of the instrument, on a trunnion 6 projecting from the back wall 4, and is .so acted upon'by a spring 7 engagingon the one hand the-back wall 1 and on the other hand the head at the inner end of the gauge 1,that its other ex tremity, which isdesigned as a handle, r0

trudes from the housing and normally a uts,

at the top against a stopshoulder 160i. the rear wall of the housing 4. Formed on orattached to the lower partofthe rear wall ofthe housing is a clamping jaw" 9, which is provided with a clamping screw 10.-' By means of this clamping jaw and screw it is quiteeasy to fix theappliance upon any plate,'preferably thecustomary looking or closing plate 1-1- (that is tosay where it will be in closeproximity and handy to the printing press) A projecting trunnion 13,011 a toothed segment 22 en-;

.the toothed segment which is pivoted at 14 in the housing'meshes with a gear wheel 15 attached to Ian indicating. disc 2l1aving a scale of figures 17 on its circumference. This scale is visible from the top through an aperture 18 in the top wall of the housing, a'reference mark 3 being. provided on the latter. A spring 20 connected on the onehand to the disc 2 and on-the other hand to'the pivot or trunnion 21 of thedisc acts to ab sorb any backlash between the disc driving wheel 15 and the toothed segment 22 and also between the trunnion 13 on the toothed seg- I ment 22' and the upper edge of the slot 12 in the gauge lever, or in other words always brings about a correct reading of the disc being fitted with an adjusting segment 24 having an arcuate slot 25, in which works a fixing screw 19, the segment being provided with a handle 26. On the curved bottom face 27 of the gauge a celluloid strip 28 is removably fixed.

V In operation the gauge at the handle" end of the lever- 8 is first pressed down and a standard block 29 corresponding to the required height of the type matter is: inserted betwe'enthe celluloid facing strip 28fand the plate 11.. The gauge lever when released adjusts'itself by reason of'the actionof the spring 7 [to the standard and gives a certain reading on the indicator disc 2, the movement of the lever 8 of the gauge around its pivot 6 being transmitted by the toothedv segment 22 and the gear'15. After loosening the fix-; ing screw 19 the eccentric boss 23 is turned the amount necessary tobring the zero-line of the indicator disc into register with the" reference mark3 on the housing, whereupon the screw 19is tightened. Nowthe standard block 29 is removed and the printing block,

theamountfof packing for which is to be ascertained is, with its printing face uppe'rmost insertedin its place- The gaugelever again moves into contact with the bloek and shows an indication on the scale 2 which diifers from the formerly adjusted zero position. Now a number of flat packing plates are inserted between the printing block and the gauge until the zero reading on the indicator disc is again reached. Then the height of the printing block together with the packing plates corresponds accurately to the re quired height, that is to say it is onlynecessary to insert the printing block with the said packing plates into the form, audit will accordingly correspond in height with the other parts of the type matter, and thus produce a perfect print. r i

The construction of the gauge in the form of a double armed lever and the use of the eccentric adjusting arrangement permits a very simple design of the whole apparatus and makes its manipulation easy.

By the use of arotating disc as the essential part of the indicating device, it is possible to extend the scale around the whole circumference, thus saving space and giving better legibility. The purpose of rounding ofl the gauge face is to enable the gauge always to lie tangentially to the standard block or the printing block and its paokings, in such a manner that the measurement is sure always to be accurate. The celluloid facing on the gauge lever protects the printing face of the block from damage, The vertical face 30 of the appliance to which the printing block can be fitted sideways, makes it possible to ascertain whether the sides of the printing block are accurately at right angles to its base, for the purpose of preventing the squeezing out when the block whose sides are not accurately square is inserted in its space in the matter, by reason of the lateral thrust then occurring. It is also possible by means of an auxiliary scale 32 starting from the zero pointto use the apparatus for measuring the exact thickness of the so-callcd printing cylinder covering, that is the soft coverings fixed to the printing cylinders for the purpose of protecting the type, such covering being ofa thickness of the order of 1 to 2' mm.

Vhen taking such measurements it is only necessary, after having put the device into the zero position in conjunction with a stand ard block to insert the said coverings between the standard block 29 and the gauge, it being then easy to read off the thickness of the covering.
